OSCAR H. DUCKWOBTH, OF SUMMEBFIELD,

BESILIENT TIRE.

Specication of Lettera Patent.

Application led August 21, 1911.

lPatented Julyz, 1912.

Serial No. 645,091.

To all whom 'it may concern.'

Be it known that I, OSCAR H. DUCKWORTH, a citizen of the United States, residing at Summerfield, in the county of Marshall and State of Kansas, have invented certain new and useful Improvements in Resilient Tires, of which the following is a specification.

My invention. relates to improvements in resilient tires, and my object is to provide a new and useful. device of this character which is adapted for use on automobile, bicycle, and other vehiclewheels Where a device of this character is desired.

A further object is to provide a tire possessing all of the advantages of a pneumatic tire, without being subject to danger from puncture, and one which is durable, easily repaired, and can .be manufactured at comparatively small cost.

Other objects of the invention will hereinafter appear, and in order that said invention may be. fully understood reference will now be made to the accompanying drawing, in which: Y

Figure 1 is a side elevation of my im-l roved tire, a portion of the casing-being 'liroken away. Fig. 2 is an enlarged cross section on line II--II of Fig. 1 and Fig. 3- is a vertical section on line III-III of Figa. l

In carrying out the invention I employ a coil-spring, preferably, of the closed cylinder type, which is wound around in a series of convolutions v1, to .forma coil tire spring 2, free to yie1d at any point. `Each convolution A1, Is held in. proper relation to its companion by an L-shap'ed retaining-member 3, and a pair of hooks 4. The L -shaped members 3 are secured to an annular saddle 5, by nuts 6Y located in an. annular groove 7 at the inner periphery of the saddle.. Hooks l are secured to a pair of resilient bands 8 en-y circling l. ring 2, as shown in Fig. l. The curved portions 4 of the hooksare of greater width than the diameter .of the coil-spring,

so that the convolutions may expand laterally when subjected to a load'. Saddle 5 has oppositely-disposed flanges 5* to prevent lateral displacement of the ring 2.

The onvolutions of ring 2, and the resilient bands 8 are protected from coming into direct contact .with the surface of the road by a casing 9 embracing the ring 2, the bands 8, and the saddle 5, said casing being held in place, preferably, by a clampmg rim 10 and a removable ring 11, which latter. is held in place upon the former by a retaining member 12. vCasing 9 also prevents the convolutions of ring l2 from becoming filled with mud or other foreign substance, and acts. more or lessvas a cushion in relieving said ring and the resilient bands 8 from undue shock when contacting with obstacles in the road.

From the foregoing description, it i5 apparent that I have produced a tire possessing the advantages above enumerated and well adapted for the purpose intended.

Having thus described my invention what l claim, and desire to secure by Letters Patent, is:

In combination with an annularsaddle having side flanges, a coil spring. formed into a series of convolutions to provide a coil tire spring which seats in said saddle, means to connect the lower end of each convolution to said Saddle, a pair of spaced .bands on opposite sides of said ring located beyond the peripheral ed es of thje side flanges of said saddle, a hoo carried b'y each band for each convolution, said hooks having curved portions` of greater WidthV than the. diameter of the coil spring so as tp permit said convolutions to expand lat rally, and a Acasing extending over .said ban( and the `side flanges of the saddle.

In testimony whereof I aix my signature, in the presence of two witnesses. n
